Dell 6400. will not start. Only green power light dimly lights
I have a Dell 6400 laptop. When I press the power switch nothing happens except that the green power indicator light shows a dim light. Plugging in the adapter with the battery in or out does not make any difference, the light remains lit. If I power on without the adapter plugged in the light shows and then goes out after a few seconds.I have reseated the RAM. If I press the test button on the back of the battery all 5 green indicator light show on the battery.
Can anyone help
